Starting with linear regression and leading to\nGeneralised Linear Models, softmax regression, and quantile\nregression. Specifically, the model-robust subsampling method\nproposed in Mahendran, A., Thompson, H., and McGree, J. M.\n(2023) <doi:10.1007/s00362-023-01446-9>, where multiple models\ncan describe the big data, and the subsampling framework for\npotentially misspecified Generalised Linear Models in\nMahendran, A., Thompson, H., and McGree, J. M. (2025)\n<doi:10.48550/arXiv.2510.05902>.",
